Windows 10: Trying to reset file extension icon to blank paper icon (no program default to open)

I am trying to reset my PC to have NO default program to open file type .dxf. Right now the icon is for MSpaint, and I can’t unselect a default program. I tried uninstalling paint but that didn’t work to reset icon either. Is it possible to set the blank white paper icon for a program AFTER changing the default program to something else. Thanks!

Ps. Paint doesn’t even open dxf files! It was the Ai icon before, I was trying to remove that icon too.

Remove Linux Desktop Icons

I am not sure whether this will work (Ubuntu does not have icons like that on the desktop by default), but I suggest opening the trash bin and sweeping the icons into the window showing the trash bin.

Fix Blank or White Shortcut Icons on Desktop

Once in a while, the shortcut icons on the Windows desktop may suddenly been changed or became blank or ‘white paper’ icon, where supposedly the icons should be colorful and customized in style and color. It’s as if the icon for the shortcut has been removed
or unassigned, and been replaced with default blank icon in white.

The bug happens whenever there is corruption in icon cache database. For example, in Windows 7 pre-RC release, a network connection or broadband connection shortcut’s icon placed on desktop by user manually will go haywire and turn into blank default icon if
there is another third-party program places an icon on desktop later.

In order to fix the problem where shortcut icons turn to blank icon, try to refresh or rebuild the cache database for icons. There are many system management software utilities that may reset the icon cache db automatically, but here’s how to reset the icon
cache db manually.

To refresh and reset the icons cache, go to the following folder:

C:\Users\\AppData\Local\

To see the hidden AppData folder, go to Organize -> Folder and Search Options ->
View tab, and select Show hidden files, folders and drives, and uncheck
Hide protected operating system files (Recommended).

Once inside the folder, delete IconCache.db. Create a new file named IconCache.db, and set it to
Read Only attribute in Properties (if the file is not read only, the cache won’t be reset). Then restart the computer. Remove the Read Only attribute of IconCache.db file, and the icons cache will be refreshed. The step will restore the desktop
shortcut icons to their lawfully icons.

Blank Thumbnails on Taskbar and Paper white images icon

Hi, After the recent update 1709 -- (The fall update I think) I've encounter issues with thumbnail previewer. I does not show thumbnail images but default icon instead




it wasn't my first time I've encountered this, It happened same thing on every updates. So knew I'd need to rebuild icon and thumbnail cache once again so I following this steps...

After Creators Update 2 thumbnails cache keeps auto-deleting Solved - Windows 10 Forums

After few restart, it did not solve my issues issues, It did not rebuild cache but went for worst. Now I got I got a blank icon/thumbnails on taskbar (left of screen) and it seem to happen only on windows store app (i.e. calendar, mail, photo previewer and etc..) not the third party programs.



I also have issues with images (almost most image format) showing paper white thumbnails, instead of previewer or default icon.




I cannot fathom how this happen. I've spend hours goggling for solution, done many different methods on rebuilding icon and reboot pc 50+ times. Went through recovery and rollback version. sfc /scannow DISM. virus screening, disk cleaning and etc none of it detect my issues and its driving me nuts.
Instead of having to reset windows and reinstall many of 3rd parties program again I was hoping there are solution. Would anyone by any chance know what the issues are? Thanks in advance.
